Marriott’s ‘Lace Market’ development is a new build comprising residential apartments and retail units in the heart of Nottingham’s Lace Market area and contains a wide range of glazing products within Norman & Underwood’s scope of works. The residential apartments to St Mary’s Gate and Warser Gate elevations, have Kawneer 601 thermally broken casement windows, these windows are required to have feature centre mullions to satisfy planning approval. The main elevation to Lace Market Square has an intricate bespoke curtain wall screen, using the Kawneer AA100 system, which contains concealed opening lights and has a very attractive white horizontal frit pattern on a grey backing panel. To meet the requirements under the planning approval a high performance glass specification had to be used, to achieve both the required U-values and acoustic values.
